JP-A-6-347047

  However, in the technique described in the document, since the flat drain pan is disposed opposite to the upper center of the cooking device, the high-temperature exhaust gas rising from the cooking device heats the lower portion of the flat surface of the drain pan. Therefore, there is a possibility that the drain pan becomes hot and the oil droplets accumulated in the drain pan are ignited.

  Moreover, in the technique described in the document, the oil smoke rising from the cooking device side is guided to the purification section through a flow path that bypasses the periphery of the drain pan, so that the temperature of the oil smoke in the flow path before reaching the purification section is lowered. Therefore, the flow path before reaching the purification section is easily contaminated with aggregated oil and fat, and the oil and fat aggregated in the flow path may become oil droplets and sag to the cooking device side. Therefore, the technique described in the document still has room for investigation in order to prevent oil droplets from dripping to the cooking device side and to solve the problem that the flow path before reaching the purification section is contaminated with oil.

  Therefore, the present invention has been made paying attention to such problems, and as much as possible to prevent the oil droplets from dripping to the cooking device side, as well as the flow path before reaching the purification unit. It is an object of the present invention to provide an oil and smoke purification device in which oil droplets accumulated in a drain pan are hard to ignite while preventing oil and fat contamination as much as possible.

And an annular drain pan in which a pool is formed.

  According to the oil smoke purification apparatus according to one aspect of the present invention, since the drain pan is annular, the vicinity of the oil reservoir around the annular drain pan is a flow path as compared with the flat drain pan disposed opposite to the upper center of the cooking device. The ambient temperature is lower than that of the central cavity. Therefore, the oil droplets collected in the oil pan of the drain pan are difficult to ignite.

  Furthermore, according to the oil smoke purification apparatus according to one aspect of the present invention, the oil smoke generated by cooking with the heating cooking appliance is guided to the purification portion from the hollow portion in the center of the annular drain pan. The oil smoke temperature can be kept relatively high. Therefore, according to the flow path configuration in the present invention, the fats and oils hardly aggregate to the vicinity of the purification unit. For this reason, it is possible to prevent as much as possible oil stains in the flow path before reaching the purification section, and to prevent as much as possible the agglomerated fats and oils from forming oil droplets and dripping on the cooking device side.

  As described above, according to the present invention, the oil droplets accumulated in the annular drain pan are difficult to ignite, and the oil / fouling in the flow path before reaching the purifying section and the oil / fat become oil droplets in the cooking device. The possibility of drooping to the side can be prevented as much as possible.

  Further, an annular drain pan 30 in which an oil sump 32 is formed is disposed inside the outer cylinder 10 at a position facing the lower end of the dust collecting cylinder 21. On the other hand, the outer cylinder 10 is provided with an annular placement portion 16 at its lower end, and the drain pan 30 is placed in a horizontal posture on the placement portion 16. The annular drain pan 30 has a circular cavity 31 having a hollow at the center thereof and an annular oil reservoir 32 in which the oil A is accumulated.

  The oil reservoir 32 is formed in an annular shape at a position facing the lower end of the dust collecting cylinder 21. The hollow portion 31 is disposed so as to be positioned on the lower side in the outer cylinder 10, and the hollow portion 31 is a flow path that guides the oil smoke G to the purification unit 20. In the present embodiment, the outer peripheral surface of the annular drain pan 30 has an outer diameter that contacts or opposes the inner peripheral surface of the outer cylinder 10 with a slight gap therebetween.

When the lock 15 is unlocked, the power supply is always “OFF” regardless of whether the power switch of the power supply unit 40 is on or off.

Next, operation | movement and effect of the oil smoke purification apparatus 1 of this embodiment are demonstrated.
The oil smoke purification apparatus 1 of this embodiment is operated when the cooking device K is used for cooking. When operating the oil smoke purification apparatus 1 of the present embodiment, the intake fan on the side of the smoke exhaust duct 2 is operated, and a power switch (not shown) provided in the power supply unit 40 is turned “ON”. Thereby, the inside of the smoke exhaust duct 2 becomes negative pressure, and the oil smoke purification apparatus 1 communicating with the smoke exhaust duct 2 sucks indoor air from the tip of the introduction tube 3. Since the leading end of the introduction cylinder 3 is opposed to the upper center of the cooking device K, the oil smoke G generated by the cooking with the cooking device K flows inside the outer cylinder 10 along the axis CL of the oil smoke purification device 1. To be introduced.

  The electric power supplied from the commercial power supply to the power supply unit 40 is supplied to the dust collection cylinder 21 and the discharge wire 23 so that the power supply unit 40 applies a DC high voltage necessary for electrostatic dust collection. As a result, corona discharge is generated from the discharge wire 23, and the oil droplet particles in the oil smoke G introduced into the outer cylinder 10 are negatively charged. Therefore, the oil droplet particles in the oil smoke G are attracted to the inner peripheral surface of the dust collecting cylinder 21 opposed in the radial direction.

  As a result, the oil droplet particles in the oil smoke G adhere to the inner peripheral surface of the dust collecting cylinder 21, whereby the oil droplet particles are removed from the oil smoke G. And the oil smoke G after oil droplet particle | grains were removed is discharged | emitted from the smoke exhaust duct 2 to the outdoor. Therefore, the indoor air is kept clean. In FIG. 2, a circle with a minus sign written around the discharge line 23 indicates an image in which the oil droplet particles in the oil smoke G are negatively charged, and a plus sign written on the dust collecting cylinder 21 side. The attached circles indicate an image in which the dust collecting cylinder 21 is positive.

The oil droplet particles adhering to the inner peripheral surface of the dust collecting cylinder 21 are gradually aggregated because the ambient temperature is lower than that of the central cavity portion 31 serving as a flow path, and the oil droplets are collected along the inner peripheral surface of the dust collecting cylinder 21. Move to A and move downward. At the lower end of the dust collecting cylinder 21, an annular drain pan 30 in which an oil reservoir 32 is formed is disposed at a position facing the lower end of the dust collecting cylinder 21, so that the oil droplet A is stored in the oil reservoir 32 of the drain pan 30. Can be stored efficiently.
In particular, in the present embodiment, the outer peripheral surface of the annular drain pan 30 has an outer diameter dimension that contacts or opposes the inner peripheral surface of the outer cylinder 10 with a slight gap therebetween. It is suitable for lowering the atmospheric temperature.

And according to the oil smoke purification apparatus 1 of this embodiment, since it is the simple structure as mentioned above, the manufacture and installation cost of the apparatus are low, and what hinders the flow of oil smoke is a suspended discharge line 23. Therefore, the pressure loss is small, and furthermore, although the high voltage is used, the current is small, so the power consumption is small and economical.
In particular, according to the oil smoke purification apparatus 1 of the present embodiment, since the drain pan 30 is annular, compared to the oil smoke purification apparatus in which a flat drain pan is disposed opposite to the upper center of the cooking device K, the area around the annular drain pan 30 is larger. In the vicinity of the oil reservoir 32, the ambient temperature is lower than that of the central cavity portion 31 that becomes the flow path of the oil smoke G. Therefore, the oil droplet A accumulated in the oil reservoir 32 of the drain pan 30 is difficult to ignite.

  Furthermore, according to the oil smoke purification apparatus 1, the oil smoke G generated by cooking with the heating cooking device K is guided to the purification unit 20 from the hollow portion 31 at the center of the annular drain pan. That is, the oil smoke temperature in the cavity 31) can be maintained at a relatively high temperature. Therefore, according to the flow path configuration in the oil smoke purification device 1, it is difficult for oil and fat to aggregate to the vicinity of the purification unit 20. Therefore, it is possible to prevent as much as possible oil stains in the flow path before reaching the purification section, and to prevent as much as possible the agglomerated fats and oils from becoming oil droplets A and drooping to the cooking device K side.

  Moreover, the oil smoke purification apparatus 1 of this embodiment can be easily cleaned when the heating cooking appliance K is not used for cooking. The operation of cleaning the oil smoke purification device 1 of the present embodiment is performed in a state where the cooking device K is not used for cooking and the cooking device K and the oil smoke purification device 1 are cooled to about room temperature. When cleaning the oil / smoke purifying apparatus 1, the power switch of the power supply unit 40 is set to “OFF”, the locking lock 15 is unlocked to open the door 13, and the side surface of the outer cylinder 10 is opened.

  In this state, since the drain pan 30 can be taken out from the open / close door 13 in the horizontal direction, the drain pan 30 can be taken out without being inclined. Therefore, the oil droplets A accumulated in the oil reservoir 32 are difficult to spill. 1 indicates an image in which the drain pan 30 can be inserted / removed in the horizontal direction from the disclosure portion of the open / close door 13.

  Also, the dust collection cylinder 21 can be easily inserted and removed from the opening of the door 13. When taking out the dust collecting cylinder 21, the outer peripheral surface of the dust collecting cylinder 21 is grasped by hand until the locking claw 22 riding on the upper surface of the first insulating material 11 comes off the upper surface of the first insulating material 11. Rotate by hand in the circumferential direction. Thereby, since the mounting state of the dust collection cylinder 21 is cancelled | released, the dust collection cylinder 21 can be moved to the axial direction of the outer cylinder 10. FIG.

Here, although the discharge line 23 hangs down from the center of the dust collecting cylinder 21, the discharge line 23 has flexibility and tiltability. Therefore, the dust collection cylinder 21 can be pulled out in the side surface direction of the outer cylinder 10 while the discharge line 23 is inclined.
And since the discharge line 23 is urged | biased so that it may always return to a drooping attitude | position along the axis line CL from the inclination attitude | position by the aligning spring 23c provided in the upper end of the discharge line 23, a drooping attitude | position is maintained. . 1 indicates an image in which the dust collecting cylinder 21 can be inserted / removed in an obliquely downward direction from the free end side of the discharge wire 23 through the opening of the open / close door 13.

After removing the dust collecting cylinder 21, the inner surface of the dust collecting cylinder 21 and the outer peripheral surface of the discharge line 23 are cleaned, and then the dust collecting cylinder 21 is returned to the outer cylinder 10 in the reverse procedure to the above. it can. Therefore, according to the oil smoke purification apparatus 1 of this embodiment, it is excellent also in the workability | operativity and maintenance property at the time of cleaning.
In addition, although the oil smoke purification apparatus 1 of this embodiment is very excellent for oil smoke purification of the cooking device where oil smoke rises, it is not limited to the oil smoke purification of the cooking device, and can be diverted to other uses. is there. For example, it can be diverted to uses for purifying cigarette smoke and incense smoke.

  As described above, according to the oil smoke purification apparatus 1 of the present embodiment, the oil droplets A accumulated in the annular drain pan 30 are difficult to burn, and the oily and dirt in the flow path before reaching the purification unit 20, and It is possible to prevent as much as possible the fats and oils from becoming oil droplets A and dripping down to the cooking device K side. It should be noted that the oil and smoke purification apparatus according to the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the oil smoke purification apparatus 1 has shown an example in which one discharge line 23 is suspended from the upper support block 26 in one dust collection cylinder 21, but the present invention is not limited to this. A configuration having a plurality of dust collecting cylinders and dust collecting chambers may be adopted. For example, the inside of the dust collection cylinder 21 may be divided into a plurality of dust collection chambers along the axis, and a discharge line may be arranged in each dust collection chamber. Such a configuration is suitable for improving dust collection performance. In this configuration, each dust collection chamber substantially functions as a dust collection cylinder.

  Here, in the case of a configuration having a plurality of dust collection chambers, each dust collection chamber is arranged radially from the center of the dust collection cylinder 21 in plan view, and the surface of the plate is the axis of the dust collection cylinder 21. It is preferable to configure with a plurality of partition plates arranged along the direction. Furthermore, in this case, it is preferable to arrange the lower end portion of each partition plate that partitions adjacent dust collection chambers in the dust collection cylinder 21 so as to face the drain pan 30.

  Moreover, it is preferable to form the lower end part (edge part of a lower end) of the said partition plate in the inclined surface which becomes high as the center side of the dust collection cylinder 21 becomes high and goes to radial direction outer side. If it is such a structure, when the oil smoke G adhering to a partition plate will move to the lower end part of a partition plate, and it will become the oil droplet A, an oil droplet will be to the oil reservoir 32 side of the drain pan 30 along the said inclined surface. A can be guided. Therefore, in the case of adopting a configuration in which the inside of the dust collecting cylinder 21 is divided into a plurality of dust collecting chambers along the axis, in order to prevent as much as possible the possibility of the oil droplet A dripping on the cooking device K side. Is preferred.

  In the above embodiment, for example, the outer cylinder 10, the dust collecting cylinder 21 and the like are formed in a cylindrical shape and the drain pan 30 is formed in an annular shape. The dust collection cylinder 21 or the like may be a quadrangular or more polygonal cylinder, and the drain pan 30 may also be a quadrangular ring or a more polygonal ring.
